A groundbreaking study published in The Lancet Planetary Health has unveiled alarming insights into the health impacts of short-term exposure to fine particulate matter (PM2.5) in India. The research, titled "Ambient air pollution and dailymortality in ten cities of India: a causal modelling study", is the first of its kind to analyze the association between PM2.5 exposure and daily mortality across ten major Indian cities, including Delhi, Bangalore, Chennai, and Kolkata.
Key Findings of the Study
Significant Increase in Daily Mortality: The study found that a 10 µg/m³ increase in the 2-day moving average of PM2.5 is associated with a 1.42% increase in daily mortality. When focusing on locally generated pollutants using advanced causal modelling techniques, this risk escalates to a 3.57% rise in daily mortality.
High Attributable Deaths: Approximately 7.2% of all daily deaths were attributed to PM2.5 concentrations exceeding the World Health Organization's (WHO) 24-hour ambient guideline of 15 µg/m³. In Delhi, this figure was even higher, at 11.5%, translating to around 12,000 deaths per year.
No Safe Threshold: The research revealed a steeper mortality risk at lower PM2.5 exposure levels, indicating that even concentrations below India's national air quality standard of 60 µg/m³ can significantly increase the risk of death.
Locally Generated Pollutants are More Harmful: The study emphasized that locally generated air pollutants—such as those from vehicle emissions, industrial activities, and waste burning—have a stronger association with increased mortality compared to pollutants from distant sources.
Implications for Air Quality Monitoring and Public Health
These findings underscore the urgent need for real-time air quality monitoring and stricter regulations to mitigate the health risks associated with air pollution. The study highlights that significant health effects occur even at lower pollution levels, emphasizing that there is no safe threshold for PM2.5 exposure.
